VoIP Services Used by Russian Cybercriminals to Aid in Fraud

Russian-speaking cybercriminals have now gained extremely easy access to VoIP (Voice over Internet Protocol) services, according to Flashpoint, whom have tracked down VoIP services being sold, leading to financial and e-commerce fraud. The problem that has to be noted is that banks, financial institutions, and online retailers cannot completely differentiate between legitimate and fraudulent buyers. There are three main services: Narayana, SIP24, and SIP Killer, all which serve different purposes for these cybercriminals.

Narayana has a list of enticing features that would lure any criminal to it in the VoIP world, including the fact it is easy and affordable. There is also support for SIP, as well as a SIM card that is based on a global system. This is for the purpose of mobile communication, with each individual buyer receiving a free iNum. Narayana is the service with the least amount of questions and, most likely, the easiest to purchase. It gets harder if the choice turns to SIP24.

SIP24 is by invite only, like an exclusive club, but with that, the consumer gets much better call quality. This adds to the appeal if it is not just about buying something quick, fast, and inexpensive. SIP24 has hopes that, because it requires an invitation, security risks will be lower. The final service is SIP Killer which bodes “call-flooding,” forcing high volumes of calls to essentially stop the traffic of VoIP services. The SIP Killer seems to be for the more serious offenders but all three have their attractive features, especially the SIP24 with the higher call quality.

Russian cybercriminals are using and abusing VoIP services for their own gain and the two problems are: who is selling these services to those who should not have access and how can companies differentiate between legit and illegitimate transaction confirmations, especially since mobile devices make geographic tracking more difficult. This is clearly something that will take an extreme crack down and even more attention to detail.
